Description
Technical field
The invention belongs to technical field of polymer materials, is related to a kind of scratch-resistant acrylic resin and preparation method thereof.
Background technology
Polypropylene（PP）Resin not only light weight, relative low price, and also there is good chemical resistance, resistance to
It is hot, and balanced mechanical mechanics property and excellent machinability, therefore it is widely used in household electrical appliances, automobile, electronic apparatus
Deng field.In increasingly fierce market competition, polypropylene-based resin is just progressively substituting the higher general-purpose plastics of some prices.So
And with the development of society and the raising of people's quality of the life, it is also proposed higher and higher requirement to the material used, poly- third
The surface scratch resistant performance of alkene material is very poor, largely reduces the aesthetic measure of product, and produce in product surface
Scratch also result in stress concentration, limit its use.Therefore, the surface scraping and wiping resistance performance for improving polypropylene material is one
Important research topic.Scratch is a kind of failure mode of material surface, and its type and mechanism are considerably complicated, and influence factor is very
More, polyacrylic molecular structure, filler, lubricant and anti-impact modifier etc. all affect polyacrylic scratch-resistant behavior.It is poly-
Propylene material to surrendering in the presence of power, produces ductility/brittle break so as to make in pressing-in force, sliding force or horizontal stroke (side)
Into scratch.Flat surface does not produce uneven light scattering and " scratch turns white " caused by scratch.
At present, the most frequently used method of acrylic resin scratch resistance is improved, is exactly to fill talcum powder, carbonic acid wherein
The inorganic fillers such as calcium, glass microballoon, wollastonite, glass fibre, then improve PP type tree by adding the method for fire retardant
The anti-flammability of fat, but this method often reduces its table after the scratch resistance of polypropylene-based resin and anti-flammability is improved
Face glossiness.In other words, this kind of method can not improve scratch resistance, the surface gloss of polypropylene-based resin simultaneously.Therefore,
Existing market is badly in need of developing a kind of high-gloss scraping-resistant flame-retardant polypropylene alkenes tree easy to process, simple to operate and balancing performance
Fat.
Common acrylic resin surface pencil hardness is extremely difficult to the requirement of scratch-resistant in 2B-HB levels.Acrylic resin
It is not fine with other resin compatibles, can easily produces phase separation, directly influences the every mechanical property and gloss of product
Degree and surface scratch resistance, this also causes the application of this based composition to be restricted.
The content of the invention
